Are you upgrading from an existing AIR runtime or installing a new AIR runtime? If you are upgrading, can you try removing the existing runtime by deleting /Library/Frameworks/Adobe AIR.framework folder and then retry installing latest AIR runtime? Thanks.
Unfortunately, I am trying to install a new runtime - I also tried copying the framework folder into the /Library/Frameworks folder and that had issues.
I wasn't having any problems with Adobe Air until I upgraded to 10.7.2. I tried to open up YNAB and it kept crashing and finally gave me an error that I needed Adobe Air...which I had had so not sure where it went. So I go to download it which is Adobe Air 3 now and it downloads but nothing happens when I click on install. After I try it several times, I have received an error window suggesting that I need Adobe Air to install Adobe Air! Need a fix quick....I need to get into YNAB to figure out what bills need to be paid!
I'm Taylor, YNAB's lead developer. We have a number of customers who are experiencing the same problem with 10.7.2 and YNAB, and we started tracking the issue down yesterday. I started a thread over here: http://forums.adobe.com/message/3970954#3970954
I'm really sorry that this is happening to you! You can learn more in the response I linked to, but here is one weird thing we've learned: If you run Firefox at the same time, users are reporting that they are able to run YNAB! I don't know what that is about yet, but we'll get to the bottom of it soon. I also have a hunch this is related to saving and restoring Windows, so I am about to advice a couple of folks to temporarily disable that feature using these instructions: http://osxdaily.com/2011/07/18/disable-mac-os-x-lion-resume-window-restore/
You can add me to the list of folks having trouble with this. Thankfully, I found this thread. The problem goes away when Firefox is on.
I was trying to use Rosetta Stone language software (which uses Air) and it wouldn't work with OS 10.7.2. At first I thought the problem was with RS, but now I realize it's Adobe.
Thank you YNABteam for the workaround! I've included the Firefox information in the bug description. A developer is looking into this issue.
I am also experiencing problems with Adobe Air. After updating to Lion 10.7.2, when I turn on my computer, the HughesStatusMeter crashes. While researching the problem on the web, I came across the post on YNAB's forum, mentioned above, that said if you run Firefox then it corrects the problem (at least until you turn your computer off and on again). This workaround worked for me. When I turn on my computer, I close out the two error messages (below), open Firefox, then open the HughesStatusMeter, it again asks if I want to restore windows. Whether I choose to restore windows or not, this time the HughesStatusMeter will work. Then I can close Firefox and the HughesStatusMeter works as normal. Hughes is also looking at this issue for me. Disabling the Restore Windows feature did not fix this issue for me. If it is any help, here are the error messages that I get when I turn the computer:
After trying many diffrent solutions, only Launching "Google Chrome" before Adobe Air Installer worked for me...
A helpful user on our forums reported that this appears to be due to graphics switching between the discreet and integrated graphics.
We are going to try telling some folks to disable discreet graphics switching to see if that helps. You can see the post linked above for more info.
Yep, we've had at least one report that disabling "Automatic Graphics Switching" in Energy Saver preferences works around this problem!
I just gave this a try, brand new mac book pro I bought last night and I'm in the process of installing apps and whatnot. Couldn't get Air 3.0 installed. I could see the crashes in the console the installer was reporting but couldn't for the life of me figure out why. Sure enough I disabled automatic graphics switching and the Air install worked fine.
I'm not sure if you would need to leave it disabled for Air apps to continue to run though, I think it's just an installation issue.
I can confirm that after using gfxcardstatus to force using discrete card I can upgrade my Adobe air to the newest lab version (3.2)
i can confirm that this works. I was having no luck installing on a brand new MacBook Pro, and now it works fine after turning off graphics switching.
I can confirm that running Google Chrome enables Adobe Air to load successfully. It wouldn't install before downloading and opening up Chrome. I made no other changes. This is on a brand new MacBook Pro.
This is kind of ridiculous, no?
Yep, disabling automatic graphics switching did it for me. Thanks for the report.
Yep, I tried installing Adobe Air on 10.7.2 multiple times. Console shows the installer crashing (below).
Go to System Preferences > Energy Saver and uncheck "Automatic graphics switching" and it the install now works.
It's just Adobe trying to get back at Apple - happens all the time.

Thanks, YNABteam - disabling 'Automatic Graphics Switching' in Energy Saver preferences worked for me too.
This also fixed an Adobe Story issue I was having -- it wouldn't load on my
